Trump: Ukrainian jet downed in Iran may be due to 'mistake'

U.S. President Donald Trump on Thursday said he had "suspicions" about the cause of a deadly commercial plane crash in Iran, and called the airline disaster "a tragic thing."

"Somebody could have made a mistake, on the other side," Trump told reporters at the White House, but he gave no other details.

"It was flying in a pretty rough neighborhood," he added.

As Trump was speaking, Reuters reported that the Ukraine airliner that crashed in Iran, killing all 176 people aboard, was most likely brought down accidentally by Iranian anti-aircraft missiles, according to U.S. officials.
